Nearly every prescription for feeding the world says we need to invest more money in science. What’s that money going to get us?

In this story we travel to Mexico, birthplace of the Green Revolution, where international scientists are working on a wide range of interventions, from hardier crop varieties to better ways to manage the soil. And we go into the field with a Mexican scientist whose grassroots work aims to put the knowledge of millions of farmers to work on improving yields.
